XXVIII. Corals and Coral Reefs [PDF]

Transactions of the Geological Society of Glasgow, 1900
T he lecturer began by pointing out that the carbonate of lime, of which the hard parts of most corals consist, has been derived in the first instance from the decomposition of such eruptive rocks as basalt and dolerite.

Upper bound limit analysis of coral reef limestone cavern roof stability incorporating a tension‐shear failure mechanism with tensile‐strength cut‐off

Deep Underground Science and Engineering, EarlyView.
For the roof of coral reef limestone caverns, a novel tension‐shear composite failure mechanism was developed. The most critical tensile crack model was identified using a hybrid optimization algorithm, and the stability of the cavern roof was analyzed accordingly.

Palaeoecology of corals and stromatoporoids in a late Silurian biostrome in Estonia [PDF]

, 2014
A middle Ludlow biostrome at Katri, western Estonia, the richest accumulation of corals and stromatoporoids in Estonia, is partly exposed in a coastal section ca. 1 m high, 150 m long. The fully marine biostrome consists of 5 layers of skeletal carbonate,

Embryonic development of the Mediterranean starfish Hacelia attenuata

Developmental Dynamics, EarlyView.
Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Stress-Related Molecular Biomarkers to Monitor the Effects of Global Changes on Calcifying Reef-Forming Organisms: A Review in the Mediterranean

Journal of Marine Science and Engineering
Molecular biomarkers are valuable tools universally used for early warning monitoring due to their ability to detect stress at subcellular scales, even before visible or lethal changes occur in organisms.

The Optical - Infrared Colors of CORALS QSOs: Searching for Dust Reddening Associated With High Redshift Damped Lyman Alpha Systems

, 2005
The presence of dust in quasar absorbers, such as damped Lyman alpha (DLA) systems, may cause the background QSO to appear reddened. We investigate the extent of this potential reddening by comparing the optical-to-infrared (IR) colors of QSOs with and ...

Impact of upwelling events on the sea water carbonate chemistry and dissolved oxygen concentration in the Gulf of Papagayo (Culebra Bay), Costa Rica: Implications for coral reefs

Revista de Biología Tropical, 2012
The Gulf of Papagayo, Pacific coast of Costa Rica, is one of the three seasonal upwelling areas of Mesoamerica. In April 2009, a 29-hour experiment was carried out at the pier of the Marina Papagayo, Culebra Bay.
